Thermal radiation effects on oscillating frequency of heat transfer of Darcy–Forchheimer nanofluid with chemical reaction and applications in machining operations

Abstract

The advancement of cutting tool components and design is presently promoting innovative developments in numerous different machining-related industries. The characteristics of nanofluid are important for machining activities such as the drilling process, grinding, rotating, milling, and cutting. Various machining procedures require distinct lubricating oils and nanofluids for cutting-edge innovations. The significant contribution of the current mechanism is to explore the fluctuating heat and mass flux of Darcy–Forchheimer chemically reactive nanofluid along a buoyancy-driven porous plate under solar radiation region. Flow through a Darcy medium has a wide range of applications such as the use of oil in various hydrothermal transfer control, radioactive nuclear disposal systems, water improvement, and filtration of water. The dimensional model is transformed into non-dimension for scaling factors. The primitive-based transformation is applied on steady and oscillatory parts for smooth algorithm in FORTRAN language machine by using an implicit finite difference method. The numerical and graphical results of velocity, temperature, and concentration are executed by the Gaussian elimination method. To enhance the frequency and wavelength, the impact of solar radiations is applied on periodic nanoparticles with Darcy–Forchheimer relation. The novelty of this proposal is to explore the wave oscillations, amplitude, and phase angle of thermal and concentration boundary layer of Darcy–Forchheimer nanofluid flow under chemical reaction and solar radiation region. It is noticed that the prominent wavelength and frequency in thermal and concentration boundary layers is generated under porous and solar radiation region. The significance of temperature variation increases as solar radiation, chemical reaction, Brownian motion, and thermophoresis increase. It is found that minimum oscillation in heat transport is observed as Pr decreases but maximum oscillation in heat transfer is sketched as Pr enhances.
